Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

Calculation of mean convective heat transfer coefficient kc of a straight pipe at an uniform wall temperature or uniform heat flux and for a hydrodynamically developed or undeveloped overall fluid flow with neglect or consideration of pressure loss influence. Note that additionally a failure status is observed in this function to check if the intended boundary conditions are fulfilled. See more information .
